Abstract (en)
[origin: EP0417579A1] The invention relates to a surge tank for a haemodialysis concentrate. In order to ensure that the concentrate pump for preparing the dialysis fluid is fed with the concentrate at a uniform pressure even when a central concentrate supply is used, the invention proposes to introduce a concentrate suction tube 7 in a cylindrical, vertically disposed vessel 1, whose lower area is provided with an inlet for concentrate and at whose upper area there is an aerating facility 4, this concentrate suction tube 7 being equipped with at least one level sensor (6) and having an admission line (10) for flushing liquid and a discharge (11) for flushing liquid. The valve (2) arranged in the concentrate inlet (3) can be alternately activated using a control facility to which signals are conveyed from the level sensor (6). <IMAGE>
